Phenotypic characteristics of Parkinson’s disease cohort members at baseline exam (2001–2007) and follow-up (2008–2010).

Abbreviations: SD = standard deviation; PD = Parkinson’s disease; yrs = years; n.a. = not applicable; n.c. = not calculated; UPDRS = Unified Parkinson’s Disease Rating Scale; MMSE = Mini Mental State Exam; GDS = Geriatric Depression Score.*P-value for t-test of fast vs. slow progressors.§P-value for t-test of deceased participants vs. slow progressors.†P-value for t-test of lost participants vs. slow progressors.**PD subscores (bradykinesia, rigidity, tremor, gait/balance) calculated according to Louis (ref 3).§§Mini Mental State Exam score according to Folstein (ref 64).††Geriatric Depression Score according to Yesavage (ref 65).缩写说明：SD=标准差（standard deviation）；PD=帕金森病（Parkinson’s disease）；yrs=年（years）；n.a.=不适用（not applicable）；n.c.=未计算（not calculated）；UPDRS=统一帕金森病评定量表（Unified Parkinson’s Disease Rating Scale）；MMSE=简易精神状态检查表（Mini Mental State Exam）；GDS=老年抑郁量表（Geriatric Depression Score）。* 代表快速进展者与缓慢进展者的t检验P值。§ 代表已故受试者与缓慢进展者的t检验P值。† 代表失访受试者与缓慢进展者的t检验P值。** 帕金森病亚量表（运动迟缓、强直、震颤、步态/平衡）参照Louis（参考文献3）进行计算。§§ 简易精神状态检查表评分参照Folstein（参考文献64）制定。†† 老年抑郁量表评分参照Yesavage（参考文献65）制定。
